摘要:
The Federal Safe Drinking Water Act (SDWA, Public Law 96‐502, as amended) directs the United States Environmental Protection Agency (USEPA) to issue National Primary Drinking Water Regulations in interim and revised forms. This article discusses the regulatory revision process and some possible upcoming changes in the regulations, both with respect to new concepts and specific contaminants. This is part one of a two‐part article on revision of the USEPA Drinking Water Regulations. Part two appears in the January 1985 issue of OpFlow.

摘要:
A valve lifting device is described which causes the valve to hang perfectly vertical for ease of removal or installation and to swivel easily on a hoisting sling for alignment. The device can be easily handled and hooked up by one person using one hand, which leaves the other handle free to signal the operator of the hoisting equipment. Method of construction and cost are detailed.
